    Fragile Safe Mode, Win 8.1

    Hi, I've been using Win 8.1 for many months, and I've quite consistently found that after a few minor changes (install/update/uninstall some small desktop program, change some setting (often not windows but some program), + normal use, that I can no longer boot to safe mode. Indeed I now keep a simple log of the changes I make so I can redo them.

    Since I use disk imaging, I revert to the last image where safe mode worked, carefully redo the same changes, testing safe mode from time to time, and making an incremental image once I've reached a useful point.

    I usually (but not always) find that when I redo the changes, Safe Mode still works. But sometimes I have to try again.

    I've not identified any pattern as to what makes Safe Mode fail; using System Restore does not seem to solve the problem.

    I have Safe Mode as a boot option as well as Win 8.1 Pro.

    When Safe Mode fails, I see disk activity after selecting Safe Mode, then a black screen, and little disk activity. Sometimes I see 'Safe Mode' flash briefly in the 4 corners.

    It is then relatively hard to get the PC to reboot normally, as it ends up in an attempt to automatically repair itself that never succeeds, and it switches off after a couple of attempts (thermal cut-off- it gets hot).

    To restore normal boot requires a sudden power off just after boot, wait, with power disconnected, then try again.

    When I can boot into Safe Mode, everything seems to work normally, and I can switch between normal boot and safe mode without problems.

    I don't recall this sort of issue with Win 7! Any suggestions? Thanks!

    I use BootUITuner from Winaero.

    Boot UI Tuner

    It loads at restart & shows options to boot to.
    Including Safe Mode.

    The new interface shows this-

    Thanks David, useful tool.

    My basic question is why I am seeing such frequent corruption of safe mode, and hence how I can prevent it. (Normal mode is unaffected). (I can add SFC /SCANNOW shows no corruption).

    Sorry if that wasn't clear.
